Answer 2

Answer:

a) = 63428

b) = 5252247

Step-by-step explanation:

a) 628X101

= (600+28)(100+1)

= 600(100+1)+28(100+1)

= 600(100)+600(1)+28(100)+28(1)

= 60000+600+2800+28

= 63428

(b) 5247X1001

= (5000+247)(1000+1)

= 5000(1000+1)+247(1000+1)

= 5000(1000)+5000(1)+247(1000)+247(1)

= 5000000+5000+247000+247

= 5252247
